In deciding the fate of someone accused of a crime, the most important testimony often comes from people who saw the crime or a fragment of it happen. Eyewitnesses often add a devastating credibility and clarity to a very confused moment in time. But today we realise that eyewitness reports can be tainted by subjectivity. This outstanding program explores the groundbreaking research of psychologist Elizabeth Loftus, as she takes us through her discoveries on eyewitness evidence, focusing particularly on her seminal study with John Palmer, Reconstruction of Automobile Destruction'. The program explores the context of the study, the experiments, evaluation and implications.
